To all whom it may concern:

Be it knownl thatI, WILLARD ERNEST MASON, a citizen of the United States of America, residing at Burnside, in the county of Hartford and State of Connecticut, have invented certain new and usefulvImprovements in 'Iype-Vl/riti'ng Machines, of which the follow.k

ing is aspecication.

The object'o the invention isl to provide a visible writing and tabulating device for typewriters of the understrike `variety sothatzthe last line written is always visible'to the operator without,raising the carriage. v p I v. v

Figure l is a perspective view of the upper partvof a typewriting'machineflooking in the direction of the arrow in Fig. 2. Fig. 2 is a sectional elevation on about the indicator line.` Fig..3 is a plan view oi the reflector. n.

The object ofthe invention is accomplished bylocating a reflector a beneath vthe platen bo an vordinary typewriter of the understrike variety. A recess c is vformed in the reflector to permit o the passage of the type to make the impression, and a guard d is located adjacent to the recess to cause the paper when first in-l troduced into the machine to ride over the reflector` without being caught by the 'edges of thisnrecess.

The reflector is secured in position by any well known means which will permit of its ready removal. flhe tabulating 'eature is provided by locating an indicator e in line with the impression point on the platen, whereby igures or characters Oi any kind, as ditto marks, can be arranged in accurate columns without continually raising the carriage or consulting the scales and without the use of intricate and delicate mechanical adjust-v ment. A'ter the firstline oi figures is struck the proper time to begin withthe second line is shown when ythe K4lirst figure is seen on the reflector in'registering position with Vthe indicator.

I claim as my invention: A 1. -The combination in a'typewrlting machine' of the under-strike varietycomprising the frame and platen,the

reector located on the frame underneath the platen, and

an' indicator on said reflector in alinement with the lmpression point on the platen. 2. The combination inv a typewrlting machine of the under-strike variety comprlsingfthe frame and platen, of a stationary reflector located on the frame yimmediately un derneath the platen, and an indicator in alinement with the impression point on the platen. y

3. The combination in a typewritlng machine of the understrike variety comprising the machine frame and type bars, the platen and the ,carriage for the platen, of a reflector seein-ed to the frame of the machine underneath said platen, said reflector having an opening `for the passage of the "type and a guard 'for ,the edge of said opening, as and for the purposes specified.

ln testimony whereof I afx my signature in presence of two witnesses. l
